Qhov siab tshaj plaws uas tsis yog-fusing tam sim no ntawm UL specification fuse yog 110 feem pua hauv; Qhov siab tshaj plaws tsis tawg tam sim no ntawm IEC specification fuse yog 150 feem pua hauv lossis 120 feem pua hauv. Lub fusing tam sim no nyob ib ncig ntawm 130 feem pua hauv; qhov tsawg kawg nkaus fuse tam sim no ntawm IEC tus qauv fuse yog nyob ib ncig ntawm 180 feem pua hauv;
Raws li cov yam ntxwv sib txawv ntawm fuses, fuses tuaj yeem muab faib ua hom nrawm thiab ncua sij hawm, thiab lwm yam: fuses ceev feem ntau siv hauv cov hluav taws xob tiv thaiv los tiv thaiv qee yam khoom tshwj xeeb rau cov kev hloov tam sim no; Lub sijhawm ncua sijhawm fuses feem ntau siv thaum lub xeev hloov pauv. Nyob rau hauv inductive lossis capacitive Circuit Court ntawm lub surge tam sim no, nws muaj peev xwm tiv taus qhov cuam tshuam ntawm cov mem tes thaum hloov mus rau thiab tawm, thiab tseem tuaj yeem cuam tshuam lub Circuit Court sai sai thaum muaj kev txhaum tshwm sim. Txhua qhov nkhaus sawv cev rau cov yam ntxwv fusing ntawm lub fuse ntawm ib qho kev qhia tshwj xeeb, sib haum rau txhua qhov A load tam sim no tuaj yeem pom nws lub sijhawm fusing. Ntau hom fuses muaj cov yam ntxwv nkhaus ntawm cov duab sib txawv.
